Case insensitivity for keys in outerjoin and ismember?

Is there any way to have "outerjoin" ignore the letter case of string "key" fields (or cell arrays of characters) in "outerjoin" (or any join, for that matter)? What about for string comparisons by "ismember"?
If not, I have to create dummy columns of my comparison fields, with all text coerced into either lower or upper case, for the purpose of joins and ismember. I'd like to avoid this extra noise in my code and my tables.

We've had a variety of requests for a "lenient" join, but there's also a variety of different interpretations of "lenient." :-) We're still trying to figure out the best way to support this sort of thing.
For the time being, adding variables to your table with standardized text is the best way to solve the problem, as you're already doing.
